ADDITIONAL INFORMATION
REVISION NOTICE
September 1, 2015 Rev1:
• Applicability has been updated to include 2016 model year Mirai, Prius, Prius C, and Prius V
vehicles.
Any previous printed versions of this bulletin should be discarded.
Introduction
Prius and Mirai vehicles are equipped with 2 types of batteries:
• Hybrid Vehicle (HV) battery
• 12-volt auxiliary battery
If Prius or Mirai vehicles are put into storage, the state of charge (SOC) of its HV battery and auxiliary
battery will gradually decrease. To prevent the auxiliary battery from becoming discharged during
storage, proper maintenance is necessary.
Please perform the following maintenance service for the HV battery and 12-volt auxiliary battery.
NOTE
• Before disconnecting the auxiliary battery, confirm the shift lever is in the “P” position and
apply the parking brake completely. The shift lever CANNOT be shifted from the “P” position
with the 12-volt auxiliary battery disconnected.
• If the negative (–) terminal of the auxiliary battery is reconnected, even if the power button
is in the “START” mode, the hybrid/fuel cell system may NOT start. In this case, push the
“POWER” button and select the “START” mode again to start the hybrid/fuel cell system (the
“READY” light is ON). If the hybrid/fuel cell system still does NOT start (the “READY” light is
OFF), refer to the Repair Manual.

MAINTENANCE OPERATION
Before Delivery
Fully charge 12-volt auxiliary battery (deliver the vehicle to
the customer after it is fully charged 12.6 V or more).
To Store for 30 Days or More
Disconnect the negative (–) terminal of the 12-volt
auxiliary battery in the luggage compartment to prevent
the SOC of the auxiliary battery from decreasing during
storage due to parasitic current.
Just After Unloading & Every 2 Months
Keep the Hybrid/Fuel Cell System ON for 30 minutes with
the transmission in the “P” position (in order to charge
the HV battery and the auxiliary battery).
* The condition also corresponds with the section titles within this SB.

Maintenance for HV & Auxiliary Batteries
Before Delivery
Fully charge the 12-volt auxiliary battery:
1. Before charging the auxiliary battery, turn OFF all lights, accessories, and the hybrid/fuel cell
system.
2. Open the back door and remove the battery cover.
3. Remove the positive (+) terminal cover.
Figure 1..

Positive Terminal Cover
4. Check the battery SOC.
• If the battery voltage is LESS THAN 12.6 V, then continue to step 5.
• If the battery voltage is 12.6 V or MORE, replace the positive (+) terminal cover, install
battery cover and close the back door.
NOTE
• If measuring the voltage with the negative (–) terminal connected, turn OFF the power
switch and turn ON the headlights for 20 to 30 seconds. This will remove the surface
charge from the battery.
• If the hybrid/fuel cell system has been running before measuring the voltage, wait 20
minutes or more after turning off the hybrid/fuel cell system. This removes the surface
charge.

Maintenance for HV & Auxiliary Batteries
Before Delivery (Continued)
Fully charge the 12-volt auxiliary battery: (Continued)
5. Test/charge the 12-volt auxiliary battery using the
GR8 Battery Diagnostic Station.
Figure 2.
.
NOTE
Be sure to use the latest GR8 Battery
Diagnostic Station software, which can be
found on TIS.
A. Connect the red charger clamp to the positive
(+) battery terminal and the black charger
clamp to the negative (–) battery terminal.
B. Plug the charger into a grounded 110-volt
nominal outlet and flip the power switch to the
“ON” position.

C. Once the charger is properly turned ON,
perform a diagnostic charge.
The GR8 Battery Diagnostic Station will
indicate result when complete.
If the battery tests bad ("Replace Battery"),
then replace the auxiliary battery.
NOTE
If the auxiliary battery was stored at 32◦F
(0◦C) or below, charge the auxiliary battery
in a room above 32◦F (0◦C).
CAUTION
• Charge in a well-ventilated area.
• Do NOT allow sparks or fire near the
auxiliary battery.
If the GR8 Battery Diagnostic Station is NOT
available, you may charge the 12-volt battery
by cycling the vehicle on to “READY.”
• Run time will vary depending on the state
of charge.

• If this method is used, you must confirm
that the battery is charged to 12.8 volts
using a DVOM.
6. After charging the auxiliary battery, install the
positive (+) terminal cover.

Maintenance for HV & Auxiliary Batteries
Every Two Months
Cycle vehicle to “READY” ON:
NOTE
• When the remaining capacity of the HV battery is low, if the vehicle is equipped with a gasoline
engine, it automatically starts and the HV battery is charged by the generator. On hydrogen
fuel cell vehicles, the HV battery is charged by the fuel cell system. The 12-volt auxiliary
battery is also charged by the HV battery regardless of the gasoline engine / hydrogen fuel
cell stack operation
• Be sure to reconnect the negative (–) terminal of the auxiliary battery BEFORE performing
this procedure.
1. If equipped with a gasoline engine, park the vehicle in open air or connect the exhaust extraction
hose to the exhaust pipe.
2. Apply the parking brake.
3. With the brake pedal depressed, push the
“POWER” button and select the “START” mode
and check that the “READY” light in the meter
illuminates when the hybrid/fuel cell system starts
(the “READY” light is ON).
Figure 6..
4. Turn OFF all lights and accessories.
5. Check that the shift lever is in the “P” position.
6. Keep the “READY” light on and charge the HV battery for 30 minutes.
NOTE
• If the amount of charging energy is small, the display may NOT indicate the energy flow.
• Ensure there is a sufficient amount of fuel for the vehicle to run for 30 minutes.
